10.11 Complete check of the residuals, continued. Refer to the previous exercise. In Example 10.13 (page 575), we checked model assumptions using a scatterplot (Figure 10.10) after log transforming the response variable.

  1. (a) Repeat parts (a) through (c) of the previous exercise using LOGINC and EDUC.

  2. (b) Do you think we can comfortably perform inference using the log transformed y? Explain your answer.
